Chelostoma distinctum is a species of solitary bee commonly found in Europe. It is characterized by its distinct appearance, with a shiny black body and vibrant yellow markings on its abdomen. These bees are known for their specialized nesting behavior, constructing nests in pre-existing cavities such as hollow plant stems or beetle tunnels. Chelostoma distinctum plays an important role in pollination, particularly of plants in the Asteraceae family.
